Conveyor belts and ambient temperature

Conveyor belts and ambient temperature

Do you know what the ambient temperature is around your conveyor belt and how much cold or heat it can actually withstand? Knowing the appropriate temperature and the best material to choose for a belt can be crucial to your company, both economically and in terms of production.

Wrong estimate of ambient temperature in nine out of ten cases

A lot of factories use conveyor belts that were not made to withstand the ambient temperature. When companies get ready to invest, nine out of ten report that the air in the facilities, the machine, or around the conveyor belt is warmer than it actually is!

In environments with extreme low or high temperatures, such as freezers or deep fryers, the exact temperature is often better monitored, since the facilities are frequently equipped with thermometers. But in most environments where the air flows around the conveyor belt, e.g. inside a conveyor oven, it is much more difficult to estimate the temperature.

Regardless if you use your conveyor belts in cold, hot, humid, or dry environments, it is important that they are suited to withstand the ambient temperature.

Consequences of using the wrong type of conveyor belt

Using the wrong type of conveyor belt can have large consequences for your company. Material that is not resistant to certain temperature will wear out faster and potentially damage the product being conveyed. The belt will also break more easily and need to be replaced more often. On the other hand, a belt that is made from a material resistant to higher or lower temperatures than necessary will generate needless expenses for your company. Therefore, you can save, or even earn money, by measuring the temperature more accurately.

The belt joint is the most critical point at higher temperatures

The temperature a belt can resist depends in large parts on the belt joint. The joint is the most critical point when the temperature is increased, and the strength of the joint depends on the belt material and joining. A conveyor belt’s resistance to low temperatures depends on the elasticity of the belt, which in turn depends on the traction layer, the cover, and joining method.

Other factors that affect your belt’s thermal resistance

Another factor that affects the resistance is the temperature of the product being conveyed. Small plastic components that are ejected by an injection molding machine and land on the belt are often hot, but cool down quickly. In this case the belt does not have to be resistant to very high temperatures. A product that is larger and denser, e.g. a loaf of bread at a bakery, accumulates heat in a different way and takes longer to cool down. The belt needs to be resistant to the heat. The roll diameter is also important for the temperature resistance of a belt, and therefore follows a recommended minimum roll diameter. Smaller roll diameters are more difficult and disadvantageous to use when they are cold.

Do you need to invest in a conveyor or power transmission belt? Remember that the ambient temperature is important! At Habasit we will give you qualified technical advice and make sure that you get a belt that is suited for your specific ambient temperature.
